alright heres the problem! I have a ex motor in my ek and i smell gas in the oil? so what could be wrong? the motor still runs fine ecpt for it now guzzles gas like a v8!

 

Bad piston rings? would be my guess

 

thats what a buddy of mine said! im just trying to get a few opions!Damn car i sware the more i try to take care of it the more down hill it goes

 

You smell gas in the oil?? Are you burning oil?

Do a compression check..

 

Your could try checking to see how much oil is passing through the breather tub. Clean the tub and go for a drive then check it again. You might need to install an oil catch can dont just stick a mini air filter on your jalve cover! Do it right.

 

yeah i open the oil cap and smell gas all up in it! i had the tube on the old intake but now i just got a bottom peice cold air peice of a type R on there so i put a little fliter on! but before i had oil in the tube and intake!

 

its doesnt burn oil but it has a leak somewhere i think its coming from the head gasket but i just replaced that ! ehh i dont know!

 

If you're not burning oil or coolant it can't be the rings or the head gasket.

A catch can should ALWAYS be placed between the crankcase breather and intake manifold. You can put a breather filter on the valve cover or attach it to the intake. The valve cover breather should only have air flow into it. If air is flowing from the valve cover to the intake there is a serious problem. You most likely need to replace you PCV valve. The only reason to put a filter on the valve cover is to prevent you from sucking dirt and debris into your valvetrain and crankcase.

Now to help solve the problem:
What brand and weight of oil are you running? You should check for a possible gas leak. The oil and fuel never come into contact. Are you running an oil additive? It may be you have a gas leak. A quick test is to change your oil. If gas really is entering the oil then you'll be able to tell right away.

 

yeah i just replaced the PCV valve! I changed the oil last today, and still i smell gas! im running a mobile 1 10w30 synthetic, but i changed to castoral synthetic today cuz i cant pay for Mobile 1 anymore !All this started when i did the Y8 manifold swap !

my GF was saying the same thing about her Hyundai. Thats weird. her car has only 6000 miles on it too. Ill let you know if we find out the problem. maybe its the same

 

alright let me know, thanks!

 

hey all,
i just swapped my intake manifold, and i have a gas odor in my car too. at first, i pinched one of my injector seals (at the fuel rail) and i had a small puddle of gas on my i/m. i replaced it, but i still smell alittle gas in my car. i also broke the fitting that the PCV valve goes into (between the #4 and #3 intake runners on the b16 i/m). so now my pcv is kinda loose. would this cause the fuel smell in my car? maybe i just need to air out my car some more...

 

If your pvc valve is loose you are going to leak oil........thats what you should be smelling if anything. Often times though when there is a leak and you have oil traces left behind it will smell until its completely burned off.

 

Do a compression/leakdown test and let us know.
